The agency looked at the Billboard Hot 100 Top 10 songs for each year from 1950 to 2009, which encompassed around 600 datapoints. Then, each artist was classified as being either White, Hispanic, African-American, or "Multicultural" (groups or collaborators with members of different ethnic backgrounds).

While it's been obvious for a long time that American pop music has a heavy minority influence, seeing it tabulated into hard numbers is nonetheless shocking (if you're white): Since 2000, Caucasians have had only a feeble presence in Top 10 music sales.

Ken Muench, Draft's director strategic planning, said, "The U.S. is undergoing a radical, fundamental shift in demographics. Consider that among 85-year-olds in the U.S., only 14 percent are a minority … while among 0-4 year-olds, 48 percent are a minority!"

Ryan Herzog added that in 1956 Pat Boone's version of "Tutti Frutti" went to No. 12 on Billboard's chart, whereas Little Richard's original -- and vastly superior -- version only made it to No. 17.

The data was presented to Taco Bell before the company commissioned a new campaign featuring a new tagline, DraftFCB tells us. Not coincidentally, the new positioning, "Live Mas," is in Spanglish.

Note: On the day this item was written, six of the Top 10 artists were either African-American or multicultural collaborations.
